Linux Distros Unpatched Vulnerability : CVE-2026-101912

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.7.1, the isInSubnet and isHostInSubnet methods in...

SUSE CVE-2026-91768

The IPv6 branch of the FastCGI client access check compares only the first 12 bytes of a 16-byte IPv6 address, so listen.allowedclients matches on a /96 prefix instead of the exact address. An attacker who can source an address sharing the first 96 bits with an allowed one passes the check and...

SUSE CVE-2026-97974

In the Linux kernel, the following vulnerability has been resolved: ipv6: null-check fib6node before accessing in ip6delrtsiblings syzbot reported a null-ptr-deref in ip6delrtsiblings 0. The stack trace hinted towards a null dereference of rt-fib6node when fn-leaf is accessed in ip6delrtsiblings...

GHSA-RPW4-54J3-4H4Q ip-address: Address6.isLinkLocal() recognizes fe80::/64 rather than fe80::/10, allowing SSRF and trust-boundary bypass to on-link hosts

Summary Address6.isLinkLocal recognizes fe80::/64 rather than fe80::/10. Link-local unicast is the whole /10 under RFC 4291 §2.4 and the IANA IPv6 Special-Purpose Address Registry, so the method returns false for every link-local address outside the one /64 that stateless address autoconfiguratio...

GHSA-2VR4-CQ9G-PVRC ip-address: no classifier recognizes the NAT64 local-use range 64:ff9b:1::/48, allowing SSRF and trust-boundary bypass

Summary No classifier on Address6 recognizes the NAT64 local-use range 64:ff9b:1::/48 RFC 8215. isPrivate, isLoopback, isLinkLocal and their siblings all return false for every address in it, so an internal IPv4 destination written through a local-use NAT64 prefix 64:ff9b:1:7f00:0:100:: for...

kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...
